Identifying HL7 V3 schemas for CDA R2

Question

The company I work for recently started a project delving into the world of HL7 messaging and data trading. We are using BizTalk Server 2010 with the BTAHL7 accelerator for 2010

Answer 1

As @Grahame stated, having the HL7 V3 schemas does not really help you implement the CDA in BizTalk. The CCD (Continuity of Care Document) is a defined set of constraints on the CDA (Clinical Document Architecture) standard.

In order to obtain the CCD schemas, you have to go to HL7. You can download the CCD spec, samples, and required schemas directly by going here, accepting the HL7 licensing agreement, and giving them your data.

Once you download the ZIP file, look inside the CDASchemas folder for the actual schema files. The CDASchemas\cda\Schemas\CDA.xsd file will act as the "root" schema.

Answer 2

CDA is not like the rest of V3, and the v3 schemas are irrelevant. I would've thought Biztalk included CDA schemas specifically. The ones you need are:

• datatypes-base.xsd
• NarrativeBlock.xsd
• voc.xsd
• datatypes.xsd
• POCD_MT000040.xsd
• CDA.xsd
